Description

Die Erfindung betrifft eine Kabeltrommel gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a cable drum according to the preamble of patent claim 1.

Auf Baustellen werden häufig zur Betonverdichtung Innenvibratoren eingesetzt, deren Asynchronmotoren mit einer Sonderspannung und einer Sonderfrequenz versorgt werden müssen. Soll zum Beispiel ein in dem Innenvibrator vorhandener Asynchronmotor mit einer angeschlossenen Unwucht eine Drehzahl von 12.000 min-1 erreichen, ist bei einer 2-poligen Maschine eine Anregungsfrequenz von 200 Hz erforderlich. Das öffentliche Netz stellt jedoch lediglich eine Frequenz von 50 Hz zur Verfügung.On construction sites, internal vibrators are often used for concrete compaction, the asynchronous motors of which have to be supplied with a special voltage and a special frequency. If, for example, an existing in the internal vibrator asynchronous motor with a connected unbalance achieve a speed of 12,000 min -1, with a 2-pole machine, an excitation frequency of 200 Hz is required. However, the public network only provides a frequency of 50 Hz.

Aus diesem Grund wurden in der Vergangenheit Frequenzumformer eingesetzt, die meist mit Drehstrom versorgt wurden und aufgrund Ihres hohen Gewichts sehr schwer zu handhaben waren. Ein Beispiel für eine derartige Anordnung zeigt Fig. 2.For this reason, frequency converters have been used in the past, mostly were supplied with three-phase current and very difficult to do because of their high weight handle goods. An example of such an arrangement is shown in FIG. 2.

Gemäß Fig. 2 ist ein Innenvibrator 1 über einen Schalter 2 und ein Kabel 3 mit einem herkömmlichen Frequenzumformer 4 verbunden. Da auf Baustellen meist größere Entfernungen zwischen der Arbeitsstelle und dem nächsten fest angeordneten Netzanschluß zu überbrücken sind, ist der Frequenzumformer 4 mit einer allgemein bekannten Kabeltrommel 5 verbunden. Von der Kabeltrommel 5 kann ein Kabel 6 abgewickelt und an den weit entfernten Netzanschluß angeschlossen werden.2 is an internal vibrator 1 via a switch 2 and a cable 3 with a conventional frequency converter 4 connected. Because on construction sites mostly longer distances between the work station and the next fixed network connection are bridged, is the frequency converter 4 with a well-known cable drum 5 connected. From the cable drum 5, a cable 6 can be unwound and to the far remote mains connection.

In jüngerer Zeit wurde es möglich, durch Bereitstellung von entsprechender Leistungselektronik mit entsprechenden Halbleitern den Frequenzumformer zu miniaturisieren und auf diese Weise sein Gewicht von beispielsweise 60 kg auf 4 kg zu vermindern. Ein derartiger leichterer Frequenzumformer wird nach wie vor zwischen den Innenvibrator 1 und die Kabeltrommel 5 geschaltet. Bei Bewegung des Innenvibrators zu verschiedenen Arbeitsstellen müssen daher nach wie vor der Frequenzumformer und zusätzlich die Kabeltrommel bewegt werden.More recently, it has become possible by providing appropriate power electronics miniaturize the frequency converter with appropriate semiconductors and in this way to reduce its weight from, for example, 60 kg to 4 kg. Such one lighter frequency converter is still between the internal vibrator 1 and the cable drum 5 switched. When moving the internal vibrator to different work places must therefore still have the frequency converter and the cable drum be moved.

Aus der DE 4405391 A1 ist eine Kabeltrommel gemäß dem Oberbegriff des Patentanspruchs 1 bekannt, in die ein Radio integriert ist, so daß die Kabeltrommel und das Radio als Einheit bewegt werden.From DE 4405391 A1 a cable drum according to the preamble of claim 1 is known, in which a radio is integrated, so that the cable drum and the radio are moved as a unit.

Die DE 8916195 U1 offenbart ebenfalls eine Kabeltrommel mit einem in der Trommel angeordneten, einsteckbaren Radio. DE 8916195 U1 also discloses a cable drum with an arranged in the drum, plug-in radio.

In der DE-GM 7641166 wird eine Kabeltrommel mit einer integrierten Leuchtquelle beschrieben.DE-GM 7641166 describes a cable drum with an integrated light source described.

Der Erfindung liegt die Aufgabe zugrunde, die Handhabbarkeit eines Baustellengeräts, insbesondere eines Innenvibrators weiter zu verbessern, insbesondere seine Beweglichkeit zwischen mehreren Arbeitsstellen.The invention has for its object the manageability of a construction site device, in particular to further improve an internal vibrator, in particular its Mobility between several jobs.

Die erfindungsgemäße Lösung der Aufgabe ist in Patentanspruch 1 definiert. Vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen.The achievement of the object is defined in claim 1. advantageous Embodiments of the invention can be found in the subclaims.

Die erfindungsgemäße Lösung der Aufgabe erfolgt durch eine Kabeltrommel mit einem drehbar auf einem Gestell gelagerten Rundling, an dem wenigstens eine Steckdose angeordnet ist und auf dem ein Kabel aufwickelbar ist, dadurch gekennzeichnet, daß an dem Rundling ein Frequenzumformer befestigt ist und daß wenigstens die eine Steckdose mit dem Frequenzumformer elektrisch gekoppelt und mit einer elektrischen Sonderfrequenz versorgt ist.The object is achieved by a cable drum with a Rundling rotatably mounted on a frame, on which at least one socket is arranged and on which a cable can be wound, characterized in that that a frequency converter is attached to the Rundling and that at least which is an electrical outlet electrically coupled to the frequency converter and with a electrical special frequency is supplied.

Durch diese Integration von Kabeltrommel und Frequenzumformer braucht bei einer Bewegung des Innenvibrators von einer Arbeitsstelle zu einer anderen zusätzlich nur noch die neben dem Kabel auch den Frequenzumformer tragende Kabeltrommel bewegt zu werden. Darüber hinaus können Bauteile und Gewicht gespart werden, da der Umformer kein separates Gehäuse und keine aufwendige Spannungsversorgung benötigt.Through this integration of cable drum and frequency converter one needs Additional movement of the internal vibrator from one job to another only the cable drum that carries the frequency converter in addition to the cable to be moved. In addition, components and weight can be saved because the converter is not a separate housing and no complex power supply needed.

Besonders vorteilhaft ist es, wenn der Frequenzumformer in dem Bereich des Rundlings angeordnet ist, der von dem Kabel umgeben ist, wenn das Kabel auf den Rundling aufgewickelt ist. Im Inneren des Rundlings, d.h. innerhalb der Kabelwicklung befindet sich meist genügend Bauraum, um den miniaturisierten Frequenzumformer unterbringen zu können. Auf diese Weise wird der von der Kabeltrommel genutzte Bauraum optimal ausgenutzt.It when the frequency converter in the range of Is arranged round, which is surrounded by the cable when the cable on the Rundling is wound up. Inside the round, i.e. within the cable winding there is usually enough space for the miniaturized frequency converter to be able to accommodate. This way the cable reel used space optimally used.

Zweckmäßigerweise wird der Bereich von einer Drehachse des Rundlings durchdrungen. Der Frequenzumformer ist daher dicht an der Symmetrieachse der Kabeltrommel angeordnet, wodurch die gleichmäßige Drehung des Rundlings beim Aufund Abwickeln des Kabels nicht beeinträchtigt wird.The area is expediently penetrated by an axis of rotation of the round blank. The frequency converter is therefore close to the axis of symmetry of the cable drum arranged, which ensures the even rotation of the round when opening and closing Unwinding the cable is not affected.

Sehr vorteilhaft ist es, daß die Umformung der Frequenz in dem Frequenzumformer im wesentlichen durch elektronische Halbleiter erfolgt. Dadurch ist es möglich, den bisher bekannten großen und schwer zu handhabenden Frequenzumformer zu miniaturisieren, daß er in der Kabeltrommel unterbringbar ist.It is very advantageous that the frequency conversion in the frequency converter essentially done by electronic semiconductors. This makes it possible to so far to miniaturize known large and difficult-to-use frequency converters, that it can be accommodated in the cable drum.

Bei einer besonders vorteilhaften Ausführungsform der Erfindung sind auf einer Stirnseite des Rundlings Steckdosen angeordnet, die elektrisch mit dem Kabel verbunden sind. Wenigstens eine der Steckdosen sollte mit Netzspannung und Netzfrequenz versorgt sein, während wenigstens eine andere Steckdose mit dem integrierten Frequenzumformer elektrisch gekoppelt und mit einer elektrischen Sonderfrequenz versorgt ist. Dadurch sind an der Stirnseite des Rundlings verschiedene Arten von Steckdosen vorgesehen, die entweder eine Verlängerung des öffentlichen Netzes mit 230 V oder 400 V ermöglichen oder den speziellen Umformerstrom, insbesondere für den Innenvibrator bereitstellen.In a particularly advantageous embodiment of the invention are on one end face the Rundlings sockets arranged, which are electrically connected to the cable. At least one of the sockets should be supplied with mains voltage and mains frequency, while at least one other electrical outlet with the integrated frequency converter is coupled and supplied with a special electrical frequency. Thereby are on Various types of sockets are provided on the face of the round, either enable an extension of the public network with 230 V or 400 V or the Provide special converter current, especially for the internal vibrator.

Je nach Ausführungsform der Kabeltrommel kann er aber auch außerhalb des von dem Kabel 13 umgebenen Bereichs angeordnet sein, so z.B. auf der Stirnseite der Kabeltrommel. Bei entsprechender Ausbildung des Frequenzumformers 15 kann er auch massensymmetrisch zu einer in Fig. 1 nicht gekennzeichneten Drehachse des Rundlings 12 angeordnet werden, so daß sein Schwerpunkt auf der Drehachse zu liegen kommt. At the core of the Rundlings 12, i.e. essentially in the area that is wound up by the Cable 13 is surrounded, a frequency converter 15 is installed.

Er wird über das Kabel 13 mit Netzspannung versorgt und wandelt diese in eine Sonderspannung und eine Sonderfrequenz, z.B. 200 Hz mit 42 V. Die von dem Frequenzumformer 15 erzeugte Wechselspannung wird an eine an dem Rundling befestigte bzw. in diesen integrierte Steckdose 16 abgegeben, an die ein Stecker 17 anschließbar ist, so daß der Innenvibrator 11 mit der Sonderspannung versorgt werden kann.The frequency converter 15 works on a semiconductor basis, which is a compact and weight-saving Embodiment allows. It is supplied with mains voltage via the cable 13 and converts it into a special voltage and a special frequency, e.g. 200 Hz with 42 V. The AC voltage generated by the frequency converter 15 is applied to a attached to the Rundling or integrated into this outlet 16, to the one Plug 17 can be connected so that the internal vibrator 11 is supplied with the special voltage can be.

Zusätzlich zu der Sonderfrequenz kann auf der Stirnseite des Rundlings 12 auch noch wenigstens eine Steckdose 18 vorgesehen sein, die mit Netzspannung versorgt wird.In addition to the special frequency, at least one can also be on the face of the round blank 12 a socket 18 can be provided, which is supplied with mains voltage.

Je nach Ausführungsform der Kabeltrommel stellen die Steckdosen 16, 18 eine Verlängerung des öffentlichen Netzes oder eine Bereitstellung des speziellen Umformerstroms dar.Depending on the embodiment of the cable drum, the sockets 16, 18 provide an extension of the public grid or a provision of the special converter current.

Die Zusammenfassung bzw. Integration der Kabeltrommel 7 mit dem miniaturisierten Frequenzumformer 15 zu einer baulichen Einheit gewährleistet eine Reduzierung der Teile, eine Verminderung des Gewichts, geringere Empfindlichkeiten gegen Feuchtigkeit und mechanische Einwirkungen und erleichtert die Bewegung der gesamten Anordnung zu verschiedenen Arbeitsstellen, da kein zusätzlicher Frequenzumformer von dem Bediener bewegt werden muß.The combination or integration of the cable drum 7 with the miniaturized frequency converter 15 to a structural unit ensures a reduction in parts, a reduction in weight, lower sensitivity to moisture and mechanical influences and facilitates the movement of the entire arrangement different workplaces, since no additional frequency converter from the operator must be moved.
